Most living organisms cannot survive at temperature at about 45°C. How are some microbes able to live in habitats with temperatures exceeding 100°C ?

Solution

Some microbes like bacteria are able to live in habitats like hydrothermal vents with temperatures exceeding 100

° C

. They derive nutrition through chemosynthesis. They have thermostable enzymes which are able to carry out the metabolic functions even at very high temperatures without degrading. Thus they can carry out all the normal functions and are able to live in such conditions.
